When we encounter an explicit timezone, we shift the time to UTC.
Because we rely on `mktime`, we need to shift it to the local time
before proceeding. If no explicit timezone is provided, local timezone
is assumed.
This fixes the "timezone-offset extension" LibJS test running on
machines with a non-UTC timezone offset.

This could aid debugging in many cases, and it doesn't break any
functionality, so let's ensure it's easier to understand in which way a
provided value is out of range.
Same as with inputs, we define outputs as a generic array of floats.
This can later be expanded to accomodate multiple render targets or
vertex attributes in the case of a vertex shader.
Previously we would store vertex color and texture coordinates in
separate fields in PixelQuad. To make them accessible from shaders we
need to store them as a completely generic array of floats.
`OwnPtrWithCustomDeleter` was a decorator which provided the ability
to add a custom deleter to `OwnPtr` by wrapping and taking the deleter
as a run-time argument to the constructor. This solution means that no
additional space is needed for the `OwnPtr` because it doesn't need to
store a pointer to the deleter, but comes at the cost of having an
extra type that stores a pointer for every instance.
This logic is moved directly into `OwnPtr` by adding a template
argument that is defaulted to the default deleter for the type. This
means that the type itself stores the pointer to the deleter instead
of every instance and adds some type safety by encoding the deleter in
the type itself instead of taking a run-time argument.
This commit ensures that the vectorscope and histogram widgets are not
updated while moving a guide with the guide tool. This significantly
improves performance for large images.
Selecting an Outline Item from the Outline view informs via callback the
corresponding Destination that has been selected. This will be used to
move the application to the corresponding page/section/etc.
This is a nice addition to the outline view, which previously simply
displayed the titles of each section. Pages are shown in the first
column, but the tree is expanded via the second column, where the title
is.
The previous implementation had some repeated code, and wasn't really
working (because the OutlineItem.parent member was never populated). In
fact, when navigating with the up/down arrows in the associted TreeView
one could experience some funky behavior.
Now that we store OutlineItem's parents, we are fixing the
implementation for parent_index(), which was comparing the parent
siblings against the item's outline item instead of to its parent.
The Value previously stored corresponded to a Reference to a Page object
in the PDF document. This isn't useful information, since what we want
to display at the end of the day is the page an outline item refers to.
This commit changes the page member on OutlineItem to be a Optional<u32>
(some destinations don't necessarily refer to a Page), which we resolve
while building OutlineItems.
While OutlineItem had a parent field, it was never populated nor used.
This commit populates it when possible (no parent means the OutlineItem
is a top-level item).
This follows the same idea that Andreas was doing in this latest videos,
where construction-time TRY()s were not present but should have been.
Like Andreas did, moving the initialisation of such fields to the
factory function, which then returns ErrorOr solves the issue.
The previous implementation of open_file had a lambda that was used to
inspect the call of ErrorOr-returning calls. This was a non-standard way
of doing this though, as the more usual and clearer way is to have an
inner function that returns ErrorOr, then handle any incoming errors on
the top level function.
This commit adds a try_open_file function, where all the logic occurs,
and all the failure-producing steps are simplied TRY'ed. The top level
open_file function takes that result and does what the lambda previously
did: showing a message box with the actual error.
Previously layers weren't compressed at all and the file size could go
up really fast in a project with multiple layers. By switching to PNG,
the situation is slightly better now.
Interestingly enough, this change won't break compatibility with old
files, as PixelPaint loads layers using ImageDecoder which will try
every codec possible. :^)
The variables 'child_to_append_after' are used to specify the child
before which new elements will be inserted, its name is misleading.
These variables are always passed as 'child' to pre_insert.
According to the spec we should return removed attribute, but the old
implementation returned nullptr instead.
Now we return the element's removed attribute.
